1) Their colors are different. Brown Fused Alumina (BFA) is brown and White Fused Alumina (WFA) is white.

2) BFA bulk density is (1.53~1.99g/cm3) and true density (3.90g/cm3). While WFA bulk density (1.75~1.95g/cm3) and specific gravity (3.95~3.97g/cm3).

3) Main raw material of BFA is bauxite, and main raw material of WFA is alumina powder.

4) Different chemical content. White fused alumina Al2O3 99% min, Na2O3: 0.3%max. Brown Fused Alumina Al2O3 :90% min and third grade content Al2O3 85%min.

5) BFA has refractory temperature 1850 Celsius degree, WFA has refractory temperature 2100 Celsius degree.

6) Although their Mohs hardness is 9.0, WFA is even harder than BFA, and BFA is more flexible than WFA.
